Facing issues with postcode 54 in a new construction?
I just bought the 13900k with an Aorous master z790 motherboard. I'm using G SKill Trident z5 32g RAM and it's having issues: when I power on, it jumps to post code 54 then restarts. If I take out the memory, it goes to post code 20 and restarts again. I think the 54 codes usually indicate a memory error, so I swapped it in with Corsair Vengeance 32. 5400 and it works the same. I'm really stuck and wish the community could assist me.
Did you attempt this step by step—one stick at a time, one slot at a time, with various options? It seems your memory isn't holding up well. Two setups didn't work, but it might be the slot issue. Also possible the board doesn't support it. Consider resetting the CMOS. If that fails, try reinserting the GPU and CPU first, as the GPU is generally simpler to swap.
It seems the setup might not be working as expected. Try repositioning the CPU, GPU, and memory modules. Also, make sure all peripherals are unplugged during testing—only connect essentials like the keyboard and GPU to see if the system can boot. If it still fails, disconnect any drives and test with just the main OS drive plus the keyboard and GPU. If nothing changes, consider ordering a replacement part.
After fixing poor hardware configuration, always reset the CMOS. When adjusting XMP memory speed, ensure all CL/CAS parameters are set to Auto before saving and resetting.
I’m running a +1 Z790 Aorus Master Rev1.0 with an i9-13900KF Corsair Vengeance DDR5 6000Mhz 2x16 CMK32GX5M2B6000C36. After power is restored (unless the PC restarts), everything lights up briefly for about five seconds. The Q-code cycles and displays 54, though I’ve noticed sequences of C-numbers like C2, C3, C4 before power cuts out suddenly. The system then restarts and boots into Windows. During a full boot I saw a 55 code flash as well. My RAM stick isn’t explicitly listed in the compatible list, but similar speed models are available. I’ve focused on enabling XMP; if it’s off, the boot is immediate regardless of the selected speed multiplier—whether auto or manual. It’s crucial to remember this issue only occurs when power was completely off before startup. If the power indicator next to the Q-code display lights up, the boot process should proceed normally.
I completed the entire reseating process, tested each stick in various positions and combinations, upgraded my power supply from a Corsair RM850i to an AX1600i after my HX1500i failed, and now use a Gigabyte 4090 Aorus Master with a water force adapter. My Gigabyte 12VHPR cable works better than adapters. After booting up, the system runs smoothly and I didn’t notice any memory issues during the extensive pre-boot memory tests.
XMP contains unique RAM overclock settings for each device model in the QVL. These are generally compatible enough to function. It seems your specific model doesn’t match the typical ones. My guess is the chip isn’t really comparable. Memory specs are often listed with just one CAS number, even though there are many more available. You’ll likely need to either overclock the CPU more than the RAM or upgrade to better RAM that’s actually listed in the QVL.
I’ve got a ticket with Gigabyte—it’d be great if they included both the good and the bad items. Anything missing would be a risk… I didn’t realize to check the quality level when I ordered the RAM; Corsair usually works fine, but my last build was an i7 4770K, so things have changed a lot since then!
